It took less than a year to build and equip the factory, employ and train the workers, and start production. The first gun was manufactured in January 1941.

Among a wide variety of weapons, ROF No. 11 chiefly produced the Bofors QF 40mm, an antiaircraft autocannon first designed in the 1930s by Swedish firm AB Bofors.

By December 1944, the factory had produced over 12,000 munitions, including anti-tank guns, Bofors guns, 20mm cannon and mortars as well as spare parts and shell casings.
